Media API v2 now returns a 400 parse error when a request contains a malformed or unsupported query parameter instead of dropping the invalid portion and returning results.

Bug Fix

Media API v2 query parameter validation: Requests to Media API v2 endpoints that include a malformed or unsupported query parameter now return a 400 response with a parse error message. 

Previously, the invalid portion of the query was dropped and the API returned a 200 with results that did not reflect the intended filter. Responses now match what was actually requested, and errors surface at the point of the request rather than silently returning unfiltered results.

Media uploaded through the CMAF VOD workflow can now be transcoded automatically into a complete rendition ladder. You no longer need to create custom renditions separately for each audio and video rendition.

New Features

CMAF VOD offers the following new transcoding capabilities:

• Automatic rendition creation: Each upload uses a transcoding config to generate its rendition ladder automatically.

• Default transcoding config: Every site receives a default config based on the standard Traditional VOD template. It creates:

  • AVC video renditions at 1080p, 720p, 540p, 480p, 360p, and 270p, capped at 60 fps
  • AAC-LC stereo audio up to 192 kbps
  • An AAC-LC or E-AC3 5.1 surround track up to 512 kbps when the source contains multichannel audio
• Source-aware transcoding: JWX preserves the source frame rate, including fractional frame rates, and maintains the orientation of vertical video. Sources are never upscaled. For example, a 720p source produces renditions at 720p and below.
• Custom transcoding configs: Work with your JWX account team to create a custom config. You can set it as the site default for all uploads or apply it to an individual media item by providing its config ID when creating the media through Management API v2. If no config is assigned to the media item, JWX uses the site default.
• Manual rendition creation: Your account team can create an empty config that bypasses automatic rendition creation. You can then create each rendition through the custom rendition endpoints.
• Rendition edits after automatic creation: A transcoding config does not lock the rendition ladder. After JWX creates the renditions, you can delete an existing rendition or use the custom audio and video rendition endpoints to add individual renditions alongside those created automatically.
• Transcoding config endpoints: New Management API v2 endpoints let you list a site’s transcoding configs and retrieve a specific config by ID, allowing you to confirm its settings before uploading media.
• Premium transcoding: Non-AVC codecs, 4K video, and audio loudness normalization require a premium transcoding entitlement and incur additional costs. If the entitlement is removed, JWX continues creating renditions with standard features and ignores any premium settings instead of failing the transcoding job.

This update helps you:

• Create complete rendition ladders without configuring each rendition individually
• Standardize transcoding across your site
• Customize transcoding for specific workflows or media items
• Retain full control over renditions, whether they are created automatically or manually.

To learn more, see the CMAF VOD overview.

NOTE: Automatic rendition creation is currently available only through the Management API v2. Support for uploading through the JWX dashboard will be added in a future release.

Use the v2 Management API to retrieve media versions and identify a media asset’s active version.

New Feature

You can now retrieve a list of media versions for a media item and get information about a specific media version through the v2 Management API.

A media version represents a distinct uploaded version of a media asset. When an asset is re-uploaded, a new version is created. Only one version can be active at a time.

FAST analytics now include a Channel ID field, making it easier to attribute streaming and ad insertion activity to individual FAST channels.

New Feature

A new Channel ID (channel_id) parameter is now available in FAST analytics, giving you a unique identifier for each FAST channel (also known as a Pop-up Channel). The parameter is populated only for VOD or live media items that belong to a FAST channel and is NULL for all other media items.

The channel_id column is available across the following analytics datasets:

• Streaming Data
• Streaming Monthly Aggregates
• Ad Insertion Data
• Ad Insertion Monthly Aggregates

FAST channel data is also available in the JWX dashboard:

• Custom reports include a new FAST Channel (Yes/No) dimension.
• The Analytics Overview page now lets you filter the Streaming and Ad Insertion tabs by FAST channel from the Media format filter.

Dashboard users can now view all motion thumbnails generated during a reupload and select one to use as the poster image.

New Feature

For reuploaded media items, dashboard users can view the motion thumbnails generated from the first 10 seconds of the uploaded video and select one to promote as the poster image.

Management API users can access this existing functionality through the List thumbnails and Update a thumbnail endpoints.

You can now upload a source file for a CMAF VOD media item and use JWX to transcode custom audio and video renditions. Previously, the CMAF VOD workflow required you to supply pre-encoded renditions.

New Features

CMAF VOD offers the following new features:

• Source file uploads: Upload an original media file through Management API v2.
• Custom transcoding: Create individual audio and video renditions from the uploaded source file, with control over each rendition’s configuration.
• Existing delivery capabilities: Deliver transcoded renditions using CMAF packaging, HLS or DASH, with or without DRM. Transcoded media also supports geo restrictions, SSAI, clipping, and streaming analytics.

This update helps you:

• Simplify CMAF VOD ingestion by uploading a single source file
• Create custom rendition ladders without pre-encoding media externally
• Use existing CMAF VOD delivery and monetization capabilities

To learn more, see our documentation. 

NOTE: Automatic rendition ladder creation and CMAF VOD source uploads through the JWX dashboard will be available in a future release.

JWX now extracts embedded Timed Text Markup Language (TTML) caption and subtitle tracks from source media.

New Feature

When you upload VOD media or perform a Live-to-VOD conversion, JWX automatically extracts embedded TTML tracks and converts them to WebVTT for delivery.

Note: TTML is supported only when embedded in source media. TTML caption files cannot be uploaded or created separately in JWX.

We've updated how playlists rank, recommend, and search for content, improving playlist experiences across web, OTT, and streaming workflows.

New Features

• Dynamic playlists now use CDN data for Plays and Trending rankings, making these sort types available for OTT experiences.
• Related playlists now use CDN data for the co-watching layer, improving related content suggestions in OTT apps.
• Search playlists can now search custom parameters using the use_params option. We've also improved exact matching, prefix searches, and case sensitivity.

You can now deliver JWX-hosted VOD media and live streams through your own content delivery network (CDN), giving you direct control over how content reaches your viewers.

New Feature

Bring Your Own CDN (BYO CDN) lets you route media delivery through a CDN of your choice, rather than the default JWX CDN. 

With BYO CDN, you can:

• Configure a custom CDN hostname against your JWX property
• Support HLS and MPEG-DASH delivery for Live and VOD content

For more information, please contact your account representative.

We’ve rebranded Bring Your Own Renditions (BYOR) to CMAF VOD, introducing an enhanced workflow with faster processing and expanded clipping capabilities for both live and VOD content.

New Features

CMAF VOD offers the following new features:

• Faster Live-to-VOD and live clipping: Convert Broadcast Live streams into CMAF VOD media with improved speed and higher-quality outputs, enabling more efficient clip creation from live content.
• VOD clipping for CMAF VOD media: You can now create new clips directly from existing CMAF VOD media items without retranscoding, preserving quality while reducing processing time.

This update helps you:

• Streamline workflows using CMAF-based media
• Accelerate clip creation from live and VOD sources
• Maintain high-quality outputs without additional encoding
